Abstract
An oil chamber at an upper portion of an outboard engine provides lubrication to a valve gear device within a cylinder head of the outboard engine. Oil passages provide engine oil into the oil chamber. Oil dropping passages on the bottom of the oil chamber permits the oil to flow vertically from the oil chamber into the cylinder head. The oil dropping passages are positioned above the valve end sections to provide sufficient lubrication to the valve end sections of the engine. As a result, the valve end sections are made from material of normal hardness, thereby reducing manufacturing costs.
